Hey all,

I'm installing this cheesy airhorn on a 2000 Tacoma TRD. I installed the speaker in the engine compartment and ran the wiring through the firewall. I have now, a ground and power wire with an in-line fuse. What are my best choices for these? I was thinking about using a bolt/washer near the pedals for the ground. As for the power wire... can someone help me with a suggestion for where to tap for key on ignition power? Where the wire is, color...

I am the novice of novi.

Thanks for the space!

Well you will need to hook up a relay. You will need to find a trigger also, did you want to use the factory horn on steering wheel or a separate button to honk air horn? If you want steering wheel switch, you will need to find GREEN/ RED wire (-) in the STEERING COLUMN and hook a wire to that and run it to pin 85 of a relay. Pin 86 can be 12+ ignition if you only want air horn to work with car running or 12v+ constant if that doesn't matter. Pin 30 of relay will be 12+ fused either ignition or constant depending on how you want to hook it up. Pin 87 will go to the air horn positive wire. Ground the horn to a factory bolt closer to driver side kick panel. You can get fancy and leave your OEM horn and add a switch to switch between air or regular horn honking.

The wire I'm test'n isn't doin' what it's supposed to be doin'... I am so glad I printed that tech sheet, with the wrong info.
Do it right the first time... or I might have to fix it for ya

Cool, thanks a lot!

I went with an Add-a-circuit, and it has it's own independent control box.
